Apigee <-SSL-> Apache Server How to hide actual url?

[#1]

Hello,

I set two-way SSL between Apigee Proxy and Apache backend server.

For example,

the url of apigee proxy is "https://apigee.com/proxy_test"

the url of apache backend is "https://example.com"

When I hit "https://apigee.com/proxy_test", it is redirected to "https://example.com".

URL address on web browser shows "https://example.com".
I want to show Apigee proxy address on the browser instead of actual url.

On ssl.conf file on Apache server, I comment out all ProxyPass and ProxyPassReverse as below.

and I stop and restarted Apache server.

How do I hide actual URL?

<VirtualHost *:443>
	...
</VirtualHost>

 <TargetEndpoint name="dev">
   ...
</TargetEndpoint>
